LIQUID-DELIVERY TAP.

Application filed April 6,

To all whom it may concern:

Be it known that I, CORNELIUS CHAMBERS, a subject of the King of GreatBritain, residing at Monkspath Priory, Shirley, in the county ofWarwick, England, have invented certain new Improvements inLiquid-Delivery Taps; and I do hereby declare the following to be afull, clear, and exact description of the same.

My invention comprises improvements in liquid delivery taps and refersto that class of such in which two delivery taps or valves areinterconnected so that two or more different liquids may besimultaneously delivered from difi'erent containers, both beingcontrolled by a single handle or equivalent. The invention isparticularly applicable for use in the delivery and mixture .of a syrupand soda water, so that the propor tions of these liquids as deliveredare con stant.

The primary object'of the present invention is to construct a tap ofthis kind which will deliver a measured quantity of the one liquid, andin accordance therewith the one tap or valve is constructed as ameasure, preferably incorporating a glass front, so that the delivery toand from the measure is visible.

Further objects of the invention will be apparent from the followingdescription.

Referring to the drawings Figure 1 is a front elevation of a liquiddelivery tap according to this invention.

Figure 2 is an end elevation thereof. Figure 3 is a plan view thereofwith the operating handle removed.

Figure 4 is a section on the line 4.4 in

Figure 2.

Figure 5 is a section on the line 55 in Figure 4.

Figure 6 is a section on the line 66 1n Figure 4.

In the construction illustrated, the main body portion 1 of the tap isin the form of a casting having two vertical tapered socket members 2and 3 adapted to receive the plug portions 4 and 5 of a tap, these twosocket members 2 and 3 being secured together by means of the integralconnecting web 6. The one socket member 2 carries a visible measuringdevice which comprises a chamber 7 formed on the front of the socket andcommunicating therewithby means of the two vertically spaced ports 14and 15 and hav- 1923. Serial No. 630,315.

ing a glass front 13 through which the passage of the liquid, say asyrup, to and from the chamber 7 may be observed.

The socket members 2 and 3 are provided with inlet pipes 8 and 9respectively, and the plug portion 4 of the syrup delivery valve has aport opening 10, which in one position comes adjacent the upper port 14of the'chamber 7 and so puts the syrup inlet pipe into communicationwith the said. measuring chamber 7. A second port opening 11 is alsoprovided in the plug 4, which when the plug has been rotated throughsubstantially a right angle, comes adjacent the lower port 15 and putsthe delivery end of 1 the plug into communication with the uring chamber7 for the discharge of the syrup, the lower end of the plug 4 being oftubular form, as shown at 12 in Figure 4.

In order to facilitate the discharge of the syrup or the like, air isallowed to pass into the upper part of the chamber 7, through the hole26 in the socket member 2, which is now in communication with the port10, and from thence through the radial hole 27 provided in the plugmember 4 to the port 14, and thence to the chamber 7.

The second plug member 5 is used to control the delivery of soda waterand is provided with a small axial hole 17 opening at its upper end intoa radial port 18 adapted to register with the inlet pipe 9. The sodawater is thus passed directly from the inlet pipe 9 to the outlet of thetap when the plug member 5 is in a suitable position.

The outlet end of the plug 5 is preferably provided with a small screwedin cap 28 having a closed end 29, a central passage 30 and two or moreradial openings 31. The object of this plug is to prevent foaming bycausing the soda water or other liquid under pressure to break into twosmall jets.

The outlets 12 and 17 of the two plug members 4 and 5 communicate withthe upper ends of the two tubular limbs 22 and 23 of a substantially Yshaped delivery member, whereby the syrup or like liquid and the sodaare discharged into the drinking vessel or tumbler, well mixed together.The two tubes 22 and 23 are secured to the lower ends of the socketmembers 2 and 3 by means of the screwed connecting collars 24 and 25.

The upper ends of the plug members 4 and 5 are provided with toothedwheels 19 and 20 meshing one with the other, the plug 4. also beingprovided with a controlling handle 21, whereby the two; plugs aresimultaneously operated.

In the normal or off position of the valves, the operating handle 21 isdisposed in the plane of the two socket members 2 and 3, the plug member5 is disposed. so that the radial port 18 is at right angles to theinlet pipe 9, and the plug member 1 disposed that the inlet port 10 isin communication with both the inlet pipe 8 and the port 1 1 leadinginto the measuringchamber 7, so that the chamber 7 is norm-ally keptfull of syrup or the like.. When the operating handle 21 is movedthrough a right angle, the lower port 11 of the plug member 4 comes intocommunication with the measur ing chamber 7 through the port 15, thesupply to the chamber 7 being simultaneously cut off. The movement ofthe handle 21 is also transmitted to the plug member 5 through themedium of the toothed wheels 19 and 21, and this plug member 5 is alsorotated through a right angle bringing the radial port 18 intocommunication with the inlet pipe 9. Thus simultaneous delivery of thetwo liquids takes place, and these are delivered to the tumbler ordrinking vessel, having been already .mixed in the junction portion ofthe two tubes 22 and 23.

Normally the handle 21 would be returned to the off position immediatelyall the syrup or the like had flowed out of the measuring chamber, inwhich case a standard quantity of soda would be supplied. If, however,more soda was required, the taps could be held open for any longerperiod desired. As soon as the handle is returned to its off position,the port 10 puts the measuring chamber 7 into communication again withthe inlet pipe 8 and the chamber refills.

What I claim then is A liquid delivery tap comprising a pair of tapbodies having laterally extending inlet passages in correspondingpositions on the sides ot the two bodies and outletpassages in theirlower ends; a measuring chamber disposed in the side of one of the tapbodies opposite the inlet passage therein, having inlet and dischargeopenings; a transparent front for said measuring chamber; a pair of plugvalves in said bodies having diametral ports, the valve in the measuringchamber body having two ports, one for the inlet and one for the outlet,and the valve in the other body having a single port, which port andsaid outlet port are arranged in the same angular relation and indifferent angular positions to said inlet port, so that said single portand said outlet port are opened together when the said inlet port isclosed and vice ve-rsa; gearing interconnecting said valves so: thatthey move simultaneously and by the same amount, and an operating handleon one of said plug valves.

In witness whereof I afliX my signature.

CORNELIUS CHAMBERS.
